It consists of different sensor with different sensing capability and different energy level. Routing is important task in HWSN from energy dissipation point of view. In HWSN many routing protocols were proposed but many protocols are for single hop communication between cluster head and sink. Here we have designed multi-hop routing protocol for HWSN, which will be energy efficient and also solve the problem of hot spot using unequal clustering. To make this protocol more energy efficient cross layer information exchange approach is used. Using cross layer communication this protocol will get residual energy, quality of link and neighboring nodes information and this information is used in cluster head selection. Moreover there is no need to do broadcast of residual energy for every round because of RDA (regular data acquisition) nodes. We can predict the energy consumption of node, which will conserve the energy using Energy Efficient Fuzzy Based Cross Layer Protocol (EEFCLP). This proposed protocol can achieve longer sensor lifetime and more energy efficiency.

INTRODUCTION Due to advancement in technological field of wireless sensor network, the concept of heterogeneous wireless sensor network is originated. HWSN is a network of node having different capabilities. Capabilities can be defined in terms of energy, sensing, coverage, deployment, link and computational heterogeneity. Such type of heterogeneity can prolong the network lifetime, improve the reliability and decrease the latency [1]. Energy is the main concern in WSN. Large amount of energy is required for communication between sink node and sensor node that is why routing is important issue in WSN [2]. As per the researchers hierarchical routing is better than flat routing for HWSN [3]. In Hierarchical routing again we are having two types first is single hop and second is multi-hop hierarchical routing. Currently routing using clustering is popular area of research in HWSN. In this clustered multi-hop routing cluster members transmit their data to the cluster head and then intermediate cluster head will relay that data to base station. In addition to multi- hop routing energy efficiency can be achieved using cross layer information exchange [4]. For example, use of RSSI information from neighboring nodes physical layer to decide next hop in route. Here in this case if signal is weak from that neighboring node then it should not be selected as a next hop on that route.
